MC74HC175DR2

Flip Flops Overview

The MC74HC175DR2 is a quad D-type flip-flop manufactured by onsemi, belonging to the 74HC logic family. It features four positive-edge-triggered D-type flip-flops with independent data inputs and complementary outputs within a single integrated circuit. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 35 MHz. Key electrical parameters include a maximum propagation delay of 22ns at 6V with 50pF load, output drive currents of ±5.2mA, and a static current consumption of 4µA. It is housed in a 16-SOIC package (0.154" width) and functions across an operating temperature range of -55°C to +125°C.

Flip Flops Procurement Notes

Verify that the specific part number MC74HC175DR2 matches the required SOIC-16 surface mount package configuration. Confirm compliance with RoHS3 standards as indicated for this variant. Ensure the supplier provides official datasheets confirming the 2V to 6V operating voltage range and the -55°C to +125°C industrial temperature rating. Cross-reference the manufacturer's ordering suffixes to guarantee the correct tape-and-reel packaging format intended for automated assembly processes.

Flip Flops Selection Notes

Select this component when designing circuits requiring multiple synchronized storage elements in a compact surface-mount footprint. The HC series offers standard CMOS performance suitable for general-purpose digital logic applications. Consider the 22ns propagation delay and 35MHz speed limits against system timing requirements. Evaluate the ±5.2mA output drive capability to ensure adequate loading for downstream logic gates without signal degradation or excessive power dissipation.

Flip Flops Part Context

This device is part of the widely adopted 74HC logic family, known for compatibility with TTL levels while maintaining low power consumption typical of CMOS technology. The MC74HC175 specifically addresses the need for multi-bit storage in space-constrained designs. Its pinout and functionality are standardized across manufacturers, facilitating design portability. The DR2 suffix typically denotes reel-based packaging for high-volume manufacturing environments.

Flip Flops Replacement Considerations

Direct substitutes include the MC74HC175ADG in SOIC-16 packaging and the MM74HC175N in PDIP-16 through-hole packaging. Texas Instruments equivalents such as the CD74HC175E and SN74HC175N offer compatible functionality. Verify pinout compatibility and electrical specifications before substitution to ensure seamless integration into existing board layouts.
